| Abstract: |
| As the current distribution devices of induction motor have l ow control precision,worse stability and unideal adjustment effect,a new dist ribution device of induction motor based on Fuzzy-PID(Fuzzy-Proportional Inte gral Differential)control is introduced.With the measured parame-ters of AC m otor,such as power factor angle,voltage and current ,the Fuzzy-PID control a lgorithm optimizes K p ,t d and t i ,and alters conduction angle of thyristor to make AC motor always working u nder electricity-saving conditions.The system operates stably and reliably,an d improves effectively the utilization ratio of electric power. |
